Structure of the I=1 nucleon-nucleon amplitudes at 6 GeV/c

Abstract

By utilising a dispersion-theoretic calculation of the isospin-zero helicity non-flip amplitude to supplement the experimental data, and by making physically reasonable assumptions about isospin-one dominance of certain helicity flip amplitudes, the authors have been able to obtain a unique, stable set of amplitudes in the region -0.7<or=t<or=-0.1 (GeV/c)2 at pL=6 GeV/c. They demonstrate how the qualitative structure of the amplitudes is determined by the data, and use their amplitudes to predict the values of observables not yet measured.
